CURRENTQINTERRUPTER.

SPECIFICATION forming part of Lette'rs latent No. 716,583, dated December 23, 1902.

Application filed Angust 29,1902. Serial No. 121,442. (No model.)

To aZZ whom it may concern.-

Be it known that I, WILLIAM SOHEIDEL, a citizen of the United States of America, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Current-Interrupters, of which the following is a specification.

This invention relates to the electrolytic form of current-interrupters, and has for its object to provide a simple and efficient current-interrupting apparatus in which the frothing over of the liquid electrolyte is prevented during a prolonged use of the apparatus and by means of which an effective and convenient adjustment of the different members of the apparatus can be had to suit the requirements of any particular use of the apparatus.

A further object of the present invention is to afiord a construction of the containing vessel of the apparatus, whereby the noise usual to the present type of interrupters in actual use is materially reduced and eliminated, all as Will hereinafter more fully appear, and be more particularly pointed out in the claims.

I attain such objects by the construction and arrangement of parts illustrated in the accompanying drawing, which represents in vertical sectional elevation an electrolytic interrupter constructed in accordance with the present invention.

Referring to the drawing, 1 represents a, supporting-base the lower end of which is preferably formed by an extended spider, as shown, to afford an extended support to the apparatus.

2 is a horizontal supporting table or shelf at the upper end of the base 1. 3 is a lateral supporting-arm attached to said base and formed of any suitable insulating material.

4: is the cell or containing vessel, preferably of the circular shape shown and which in the present construction is formed of avery thick annulus of metallic lead and which is provided with a bottom portion of lead or other suitable material. I have found from actual experience that with such thick and heavy form of the inclosing walls of the containing vessel the noise due to vibration in actual use of the apparatus is reduced in a very material degree and in some cases almost wholly eliminated. As so constructed the containing vessel 4 constitutes the cathode member of the interrupter.

5 is the anode member of the interrupter, formed by the usual Wire-point of platinum or like substance inserted in the end of the rod-shaped holder 6, as shown. Such holder .is formed of metal or like conducting material and forms parts of the circuit of the apparatus.

7 is a tube of insulating material adapted to house the anode member 5 and provided with a small orifice at its lower end, through which the point of the anode projects into the electrolyte, as usual in the present type of interrupters. In the present construction the tube 7 is provided with an enlarged chamber 8, intermediate of its vertical length, and such chamber is in turn provided with one or more lateral outlet-openings 9, as shown, the construction being such that the said chamber is adapted to intercept the liquid electrolyte that foams up said tube during an active operation of the interrupter and return said liquid electrolyte back into the containing vessel, and thus prevent the usual foaming of the same over the top of said tube and over the adjacent external parts of the apparatus.

10 is a vertical post or column attached at its lower end to one arm of the spider of the main supporting-base.

11 is a lateral supporting-arm, one end of which'is secured in an adjustable manner to the column 10 by an open-sided eye 12 and a clamping-screw 13, while the other end is formed to receive the upper end of the insulating-tube 7 and is clamped thereon by the clamping-screw 14 or other equivalent clamping means.

15 is a stationarytubularvertical post, preferably of a non-circular form, as shown, and which is secured at its lower end to the insulated lateral supporting-arm 3, before described.

16 is a vertically-adjustable tube, preferably non-circular in form and arranged to slide in the tube 15 and be guided vertically thereby.

17 is a vertically-arranged adj usting-screw arranged with the tube 16 and. turning in bearings formed at top and bottom of the same, as shown, so as to be held against independent vertical movement with relation to said tube 16.

18 is an internally-screw-threaded bushing secured in the bore of the vertical guide-post 15 and adapted to have operative engagement with the screw-threaded lower end of the adjusting-screw 1'7, the arrangement being such that a rotation of the said screw in one direction or the other will cause the tube 16 a corresponding upward or downward movement in a positive manner.

19 is a hand-wheel or head at the upper end of the adjusting-screw 17 for convenience in rotating the same.

20 is a lateral supporting-arm secured at one end to the upper end of the guide-tube 16, with its other end formed to receive the upper end of the anode-holder 6, which is secured in a vertically-adjustable manner by means of an eye formation 21 on the end of said supporting-arm and a clamping-screw 22, as shown.

23 and 24 are the respective terminals or binding-posts of the apparatus.

The circuit of the present apparatus, starting with the binding-post 24, is as follows: from such binding-post 24, through the stationary post 15, the adjustable tube 16, arm 20, and holder 6 to anode member 5, thence through the liquid electrolyte to the leaden holder or cell 4, constituting the cathode element and to which the other binding-post 23 is connected.

25 is a layer of heavy mineral oil or other equivalent oil arranged above the liquid electrolyte and adapted to protect the same from the atmosphere, so that the same will not absorb gases from the atmosphere, which would have an injurious or destructive action upon the anode.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a current-interrupter of the character herein described, the combination of a containing-cell, a contained liquid electrolyte, an anode element, and an insulating-casing inclosing the holder portion of the anode and formed with an enlarged chamber intermediate its vertical length in the wall of which chamber is formed an outlet-orifice, substantially as set forth.

2. In a current-interrupter of the character herein described, the combination of a containing-cell, a contained liquid electrolyte, an anode element, an insulating-casing inclosing the holder portion of the anode, means for adj usting the said anode vertically, the same comprising a stationary tubular post, a vertically-movable tube guided in said post, an adjusting-screw journaled to rotate in the movable tube and adapted to have operative engagement with a screw-threaded bushing in the stationary post, and a lateral arm secured to the upper end of the movable tube and adapted to carry the anode-holder, substantially as set forth.

3. In a current-interrupter of the character herein described, the combination of a containing-cell, acontained liquid electrolyte, an anode element, an insulating-casing inclosing the holder portion of the anode, means for adjusting the said anode vertically, the same comprising a stationary tubular post, a vertically-movable tube guided in said post, an adjusting-screw jourualed to rotate in the movable tube and adapted to have operative engagement with a screw-threaded bushing in the stationary post, and a lateral arm secured to the upper end of the movable tube and means on said arm for adjustable connection to the anode-holder, substantially as set forth.

Signed at Chicago, Illinois, this 26th day of August, 1902.

WILLIAM SOHEIDEL.
